Application ined .nine .10,

This invention relates to new vand useful improvements in a counter flow condenser.

One object of theinvention is 'to provide an apparatus of the character described for condensing vapors and whereby a cooling fluid may be readily supplied to the condenser coils.

Another object of the invention is to provide an apparatus ofthe character described whereby a cooling fluid may be applied for condensing vapors, said cooling fluid and vapers being circulated, one through condenserk coils and the other about said coils.

A. further feature of the invention is to provide an apparatus of the character described whereby the velocity of the flow of either the vapor to be condensed or the cooling fluid may be varied to effect the necessary heat eX- change to accomplish the desired result.

With the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification, and illustrated in the accompanying drawings, wherein Figure l shows a plan view of the device, showing the cover removed, and

Figure 2 shows a vertical sectional view thereof.

Referring now more particularly to lthe drawings, wherein like numerals of reference designate similar parts in each of the figures the numeral l designates an enclosed box-lile easing, having the end compartments 2, 2. formed therein by the solid end partitions i5, 3, leaving return bends exposed, or the horizontal baffles can be extended through to each end of boX.

rlhere. are the inlet and outlet manifolds ety and 5 in the respective compartments 2, and a series of' coils 6 connect these manifolds. As shown the respective coils of this series are disposed in parallel vertical planes, but if de sired they may be arranged in horizontal planes, or may be worm type coils.

Spaced apart between the end partitions 3, 3, and extending from top to bottom of the casing are the vertically disposed baffles 7 arranged in staggered relation. These baffles are secured to the respective sides of the casing l with their alternating free ends falling short of the opposite wall to provide the ports', or passageways 8, around said freev ends. The respective turns of the coils pass 1926. Serial NO. 114,955.

through these baffles and forni fluid tight joints therewith, if desired. Y

Spaeed apart between the top and bottom ofthe casing l and extending from side to side thereof are the horizontal partitions 9. also arranged in staggered relation and seL cured to the respective vertical end partitions 3, 3. These partitions are disposed between the Aturns of the coils 6 and their alternating free ends fall shortfof the opposing partition 3 to provide the ports yor passageways 10 around their free ends.

The cooling fluid may be introduced into the bottom of the casing at one end through the inlet pipe ll and will flow transversely back and forth in a general zigzag1 course beneath the lower partition 9, between the baf lies 7 to the other end of the casin g and then will rise to the next level and continue to flow transversely back and forth ascending from level to level as it passes around the free ends of the partitions Q'and finally is discharged from the top of the casing through the outlet l2. This cooling fluid passing around the coils will cau-se a rapid condensation within the coils. The top of the casing may be open, if desired, but will preferably be closed, and if closed the velocity of the cooling fluid may be varied to obtain the desired results.

lt is also possible to circulate the cooling fluid through the coils with the vapor to be condensed, circulating around them and in such case the condensation willform on the coils and drop back into the casing and may be drawn off in any obvious manner desired.

lifhat l claim is zP l. A counter flow condenser including an inclosed casing, manifolds within the casing, one located at each end thereof, a series of coils connected into said manifolds, the coilsA being disposed in parallel planes, end partitions extending from side to side and from top to bottom of the casing and spaced inwardly from the respective ends of the cas ing, spaced partitions extending from the top to bottom of the casing forming haines disposed in staggered relation, said baffles being secured to the respective sides of the casing with their alternating free ends falling short of the opposite wall to provide a passage around saidy free ends, the respective turns of the coils passing through the end partitions and baflles and forming fluid tight `ioints therewith, horizontal partitions spaced apartbetween the top and bottomy of the casing and extending from side to side thereof, arranged in staggered relation, and secured to the respective Vertical batlies said horizontal partitions being disposed between the turns of the coils and their alternating free ends falling short of the opposing end partitions to provide passageways around their free ends, an inlet in the bottom of the easing` at Aone end and an outlet leadingl from the top of the easing at the other end.

2. A counter How condenser includingl an inelosed easing, partitions across the easing spaced from the 4ends thereof to form end compartments, a manifold in each eompartment and a series oit coils connecting said manifolds, the coils being disposed in parallel planes, battles spaced apart between the partitions and disposed in parallel planes, said baiiies being secured to the respect-ive sides of the easingl with their alternatingl tree ends :falling` short of the opposing side of the easing forming a passage'around said tree ends7 horizontal partitions spaced apart with the free ends of said horizontal partitions falling short of the opposing transverse end partitions providing a passageway around said free ends or said horizontal partitions, an inlet entering` the casing bottom near one end thereof and an outlet leading' from the top of the easing near the other end thereof.

' In testimony whereof I have signed my naine to this specification.
